l IMPROVEMENT IN FLUTING-MACHINES.

Specification forming part of Letters PatentnNo. 1 30,413, dated August1K3, 1872.

Specification describing a new and useful Improvement inFluting-Machines, invented by EDWARD MORTIMER DEEY, of New York city, inthe county and State of New York.

First, it consists of a construction of hollow rollers havinggas-burners in the hollow spacesv for heating them, calculated toprevent the cutting off of the air-supply for combustion by theaccidental closing of the hollow ends of the rollers by the goods beingruffled. Second, it consists of an arrangement of supports for thegas-tubes, by which the supports therefor,.heretofore used at the endsof the rollers, where the goods to be ruffled are presented, and whichhave to be removed each time the rollers are, are dispensed with.Thirdly, it

consists of a very efcient and reliable arrangement of apparatus forsuspending theupper roller-support and raising and lowering ift also,the adjustable pressure-sprin gs there- Figure l is a side elevation ofmy improved dating-machine. Fig. 2 is a transverse sectional elevationtaken on the line :v .r of Fig. 1. Fig. 3 is a longitudinal sectionalelevation taken on the line y y of Fig. 2. Fig. liis a sectionalelevation taken on the line z z, Fig. 3.

Similar letters of reference indicate corresponding parts.

In Hating-machines of the character of the one here represented the endA of the lower roller B has been arranged in a bearing in the end of anarm projecting from the stand C a short distance above the base D, whichsaid arm I propose to dispense with by having a short stand, E, rise upfrom the base D under the roller, and a bearing piece, F, for thejournal G of the roller, bolted to the said stand, the said bearingpiece being made adjustable vertically, if preferred, to adjust it fromtime to time, as the roller may settle by wear of the journal and thebearing, if they should wear. This arrangement does not require as muchmetal as the other, and facilitates the forming of the mold for castingthe frame.

My improvement in the rollers to prevent the extinguishing of the flameby the accidental closing of the hollow ends of the rollers, by thegoods under treatment coming against them, consists ofthe holes H (seeFigs. 1 and 3) through the sides of the journals, or they may be at anyconvenient point near the journals. I propose to attach strong tubularsup.- ports I for the r gas-pipes K to the wall of the chimney L,projectingy inward or along the hollow rollers far enough to whollysupport the said pipes within the rollers, as clearly shown in Fig. 3,so that no support is needed for them at the end A of the rollers,which, however arranged, must seriously interfere with the removal ofthe rollers, which is frequently required. For supporting the frame M,which carries the upper roller, I propose to have long substantialguiding and supporting tubes N project downward from the arm Ocoincident with the holes for the rods P, and the hubs .or elevations Qsurrounding said holes for said rods on the upper side of said arm, andabove these hubs I have a lifting-bar, It, through which the rods go,and in which they are held by adjusting-nuts S, which said rod rests onthe said hubs when the upper roller B1 is down in the working position,being held thereon by the pressure-springs T coiled around the rods andthe tubes N below the arm O, and contracted between the said arm and theadjusting-nuts U, screwing on said rods and serving to vary the tensionof the springs to press the upper roller on the lower roller with moreor less force, as required. The said bar is lifted up to release thegoods from the rollers by lifting the upper one by the cam-lcv er V. Bythe nuts S the rods and the upper roller may be raised or lowered, aspreferred, so as to allow said roller to mesh more or less into theother one, or hold it as far above as may be required for fine or lightgoods that might be injured by corrugating too deeply orvpressingbetween the rollers too hard. The lower roller is geared with thecrank-wheel E by a train of three cog-wheels B, C', and D', the middleor idle wheel being intended to have the rollers turn in the rightdirection for drawing the goods in from the operator while turning thecrank from left to right by the right hand when having the machine infront so as to guide the goods with the left hand; but, in order thatthe machine may be worked with foot-power, the crank-wheel E is providedwith a grove for a belt, F2, to be worked from a driving-pulley below;and, in order to have the 4necessary leverage and tension of the belt onsaid wheel, I make it large and reduce the wheels D and C, below thesize of the wheel B X on the roller. Both the bearings F and F1 for thefree ends of the rollers are attached to their supports by screws, so asto be readily taken off, and the bearings Fz and F3 at the other endsare so that the roller-journals can be readily put in or taken out bymoving the rollers longitudinally when said bearings F F1 are taken off,so that I can, with but little delay or inconvenience, remove theluting-rollers and put in smooth ones of similar size and form to theiluted ones, and thus have a machine readily convertible from the onecondition to the other, by which its usefulness is greatly increased.The Wheel B1 slips on andA o the journal of the long roller readily asit is put in the bearing and taken out, and said journal is extendedbeyond the end ofthe upper roller to receive said Wheel, also tocorrespond with the bearing F2 for it, which is suiciently widened toafford room for the Wheel in a vertical slot, B2, provided therefor, theWalls of which confine the said wheel so that no fastening is needed toprevent it from Working out of place in the endwise direction of thejournal.

My improvement in the rollers for preventing the accidentalextinguishing of the flameis alike applicable to the smoothing-rollersfor which my machine is adapted, and I propose to apply it `to suchrollers.

Having thus described my invention, I claim as new and desire to securebyLetters Patent- 1. The hollovsr rollers with gas-heatin g apparatus,provided with holes H through the sides to admit air for combustion,substantially as specified. l

2. The gas-pipes supported within the holloW rollers from the frame atone end of the rollers by the tubular supports I, substantially in themanner described.

3. The combination of the upper roller support M, rods P, tubularsupports N, arm O,

bar R, lever V, and the adjustable pressure# springs T, substantially asspecified.
